1 Claim.

This invention relates to improvements in ball cocks for water closetflush tanks and relates,

more particularly, to the fulcrum lever, links, float ball lever andconnections having to do 5 with the operation of the ball cook or valve.

The object of the present invention is to simplify the system of fulcrumlever, float ball lever, and links by which the valve is operated and torender it easier to disconnect and swing back these parts to affordaccessto the ball cock. Whereas constructions heretofore in common usehave required two thumb screws and a link or links connecting the floatball lever with the fulcrum lever, on the other hand, my presentimprovements do away with one of these screws and the link-connectionaforesaid and provide pivoted links directly connecting the float balllever to the ball cock body.

In my improved ing lost.

A practical embodiment of the invention is hereinafter described and isshown in the accompanying drawing, in which:

Figure 1 is a side elevation; and

Fig. 2 is a similar view taken at right angles to Fig. 1, the ball cockbody and upper part of the hush-tube being in section, full linesrepresenting the fulcrum lever, links, and float ball lever in positionfor use, dot-and-dash lines showing how these parts may be swungbackwardly, without detachment, by removing the single thumb screw.

The upper part of the ball cock installation being the only part havingto do with'the present invention, the lower part by which the ball cockis connected to and supported by the flush tank, is not shown.

the bottom of This application is a continuation in part of myapplication Serial No. 529,198, filed April 10, 1931, now Patent No.1,999,904, granted April 30, 1935, and is also a division of myapplication Serial No. 621,488, filed July 8, 1932.

The water supply tube 3 is supported on the bottom of the flush tank andis surrounded by the hush-tube 4. Connected to the upper part of thehush-tube 4 by screw threads, is the ball cock body 5.

7 The ball cook or valve 6 is provided with a washer I and with apacking 8.

The upper end of the supply tube 3 is screw threaded at 9 for engagementwith screw threads ll! of the cushioning worm ,or spiral II which 5snugly fits the interior of the hush-tube t and is provided with a valveseat, I3 on which the washer 1 of the ball cock or valve 6 normallyrests to prevent passage of water from the tube 3 into the body 5. Holesl4 extending through the headlZ, permit water toflow when the valve orball cock 6 is raised, the water passing in to the space l5 and thenceinto the interior I6 of the hushtube 4.

The' operating means for the ball cock or valve 6 embodies a fulcrumlever ll, a float ball lever 18, which is pivoted thereto at IS on apivot,a pair of'links 20 which are pivoted at 2| to the float ball leverl8 and are pivoted at 22 to an 20 ear 23 on the ball cock body 5, and asingle thumb screw 24 by which the fulcrum lever i1 is detachablypivoted'to a pair of ears 25' on the body 5.

Heretofore, in addition to the thumb screw for 25 pivoting the lever l1to the body 5, there has been provided a pair of links integral with thesaid body, to which links the float ball lever I8 has been'pivotallyconnected bya second thumb screw, necessitating the provision of twothumb 30 screws, and the employmentof a linkage between the fulcrumlever and the floatball lever. With the old construction, both of thethumb screws have had to be removed, completely detaching the levers,when access to the ball cock became 3 necessary. The detachment ofthelevers often resulted in loss of the thumb screws and, in addition,the links or lugs integral with the body have been in the way of accessto the ballcock.

My present improvements overcome these de- 40 fects, as it will be seenthat it is only necessary to remove the single thumb screw 24 to permit7 the entire operative system to be thrown back, as shown indot-and-dashlines in Fig. 2, completely clearing the top of the appliance andpermitting ready access to the ball cook or valve.

Preferably, the connections l9, 2!, '22 are riv-' ets so that the partscannot become detached.

The lever l1 co-operates with the ball cock or valve 6 and, as shown,this co-operation is effected through the medium of a loop or open car40 on the ball cock or valve 6 through which loop passes the lever 11.

What I claim is:

tion with a valve body, of valve operating means disposed above the bodyhaving permanent pivotal or hinged connection with the body and anadditional single releasable connection with the body 5 enabling saidvalve operating means to be bodily swung back on'said pivotal or hingedconnection when said single releasable connection is released, saidvalve actuating means then being supported from the body by the hingedconnection aforesaid.
